I really don't think this is sufficient. First because SLs don't work for a network that has any connection to another network (it doesn't have to be the public Internet), and second because it says nothing at all about the problems with SLs. I suggest Site-local addresses are designed to be used for addressing inside of networks which have no connections to external networks. Other networks need to provide global addresses to their nodes. Use of site-local addresses on networks with external connectivity (especially in the absence of global addresses) is known to cause problems for some applications, and such use is currently not recommended. This recommendation may be changed once the implications of application use of site-locals are better understood. When using site-local addresses, a subnet ID may be up to 54-bits long, but it is recommended to use at most 16-bit subnet IDs, for convenience of subnet management. -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
